Max Line Length

View Source

Lines should not exceed the defined length limit.

Note

Prior to version 5.0.0, this rule was named elvis_text_style:line_length; (see elvis_removed_rules).

Exceptions

Comment lines may be excluded from this constraint, with the option skip_comments.

Quick fix

Use an Erlang code formatter that enforces strict line length limitations.

Options

  • limit :: pos_integer()
    • default: 100

  • skip_comments :: false | any | whole_line

    • default: false - emits a warning for every line exceeding the limit
    • any - no warning is emitted if the portion of the line exceeding the limit is part of a comment
    • whole_line - no warning is emitted if the entire line that exceeds the limit consists solely of a comment.
  • no_whitespace_after_limit :: boolean()
    • default: true - emits a warning when there is whitespace beyond the configured limit
    • false - allows exceptions, such as long URLs, to extend beyond the limit without requiring line breaks

Example configuration

{elvis_text_style, max_line_length, #{
    limit => 100,
    skip_comments => false,
    no_whitespace_after_limit => true
}}
